WARNING This product is not designed or rated for ensuring safety of persons. Do not use it for such purpose. Adjusting Indicators * The following graphs indicate the status of each operating level. * Be sure to use the E3T within the stable operating range. Stability indicator (green) Precautions for Correct Use Do not use the product in atmospheres or environments that exceed product ratings. Wiring The maximum power supply voltage is 26.4 VDC. Before turning the power ON, make sure that the power supply voltage is not more than maximum voltage. Load short-circuit protection The E3T incorporates a load short-circuit protection function. If the load short-circuits, the output of the E3T will be turned OFF. Then, recheck the wiring and turn on the E3T again to reset the load shortcircuit protection function. The load short-circuit protection function will work if there is a current flow that is 1.5 times larger than the rated load current. When using a capacitance load, be sure that the inrush current will not exceed 1.5 times larger than the rated current. Light Do not apply AC power to the E3T, otherwise the E3T may rupture. Stable operation range* Operating level x 1.2 Unstable Operating operation level range* Operating level x 0.8 Stable operation range* Operation indicator (orange) E3T-@@@1 E3T-@@@2 E3T-@@@3 E3T-@@@4 ON ON OFF OFF ON OFF ON * If the E3T's operating level is set to the stable operation range, the E3T will be in most reliable operation without being influenced by temperature change, voltage fluctuation, dust, or setting change. If the operating level cannot be set to the stable operation range, pay attention to environmental changes while operating the E3T. Use of E39-E10 Sensitivity Adjustment Unit (Dark-ON: E3T-ST12) (At Min.) (At Center) (At Max.) Indicator Adjuster Mounting When mounting the Sensor, never strike it with a heavy object, such as a hammer. Doing so may reduce its watertight properties. Use screws with spring, flat, or toothed washers to secure the Sensor. Tightening Torque M2-mounting Sensors: 0.15 N*m max M3-mounting Sensors: 0.5 N*m max Small Cylindrical Sensors: 1 N*m max Attachment to Moving Parts To mount the Photoelectric Sensor to a moving part, such as a robot hand, consider using a Sensor that uses a bending-resistant cable (robot cable). 1. Mount the Unit on the Receiver. 2. Set the adjuster of the Sensitivity Adjustment Unit to Max. (Before shipping: Max.) 3. After mounting on the Sensor, adjust the optical axis and secure the Sensor. 4. Place a workpiece between the Emitter and Receiver and gradually turn the adjuster counterclockwise toward the Min. side. Stop turning the adjuster when the operation indicator and stability indicator (green) turn ON. 5. Remove the workpiece and confirm that the operation indicator is OFF and the stability indicator (green) is ON. This completes the adjustment. Note: If the light attenuation rate due to a workpiece is 40% or less, the stability indicator will not turn ON whether or not light is received. When the variation of light is small such as when sensing semi-transparent workpieces, carefully perform preliminary testing. E3T-CD@@ Sensitivity Adjustment Use the special screwdriver that is provided with the Sensor to adjust the sensitivity. Do not exceed 0.8 N*cm when turning the adjuster. Others Do not use the product under the following conditions. * In the place exposed to the direct sunlight. * In the place where humidity is high and condensation may occur. * In the place where corrosive gas exists. * In the place where vibration or shock is directly transmitted to the product. 15 E3T (Unit: mm) Dimensions Tolerance class IT16 applies to dimensions in this datasheet unless otherwise specified.
